As answered by people managing Holocron and Diffyn.
Holocron's answer
Holocron is an open source docs site generator that runs as a Vite plugin in your own repo. You write MDX, put navigation in docs.json, and host the build on Vercel, Cloudflare, Node, or anywhere. Docs maintenance can run in GitHub Actions when source files change.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Holocron's answer
Closed docs platforms keep pages in their cloud. Holocron stays in your codebase. Same docs.json and MDX also work as a Mintlify drop-in, so you can leave a hosted docs platform without a rewrite.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
Holocron's answer
Vite, MDX, TypeScript, React, and a docs.json config. Search uses Orama. You can host the output on Vercel, Cloudflare Workers, or Node.
Diffyn's answer:
React, Next.js, POSTGRESQL
Holocron's answer
Teams that ship software docs next to the code. Developers who want search, OpenAPI pages, dark mode, and markdown routes for agents, and who host on Vercel, Cloudflare, or their own server.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Holocron's answer
Documentation maintenance is not an off-the-shelf hosted product. Holocron started as a Vite plugin so you can build delightful docs websites locally, keep MDX in git, and update pages from GitHub Actions with OIDC.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
